still using yor code for reference, as i think you have done a brillant job with this app.

are there any *.wxs files or xrc for the graphic GUI development?

What tool did you use for creating the GUI(graphical) side of wxwidgets?

i have been using wxsmith via codeblocks which creates .wxs files for future GUI changes.

currently looking into how you change the up/down arrow in grid/list and how data is changed when user clicks the list header, Not fully understanding how this was done yet.

are files that have panel in the file name, like "mmcheckingpanel.cpp" included into other window frames that will have a place holder in them ? like an user control in VB or .NET?
